"The Hua-yen tradition was developed by a series of thinkers, most notably Fa-tsang (CE 643-712). Through him, it passed on to Korea and other East Asian countries, becoming known as 'Kegon' in Japan. Hua-yen is praised as the highest development of Chinese Buddhist thought. D.T. Suzuki called Hua-yen the philosophy of Zen, and Zen the meditation practice of Hua-yen. Francis Cook explains the core philosophy of Hua-yen as follows: 'Far away in the heavenly abode of the great god Indra, there is a wonderful net which has been hung by some cunning artificer in such a manner that it stretches out infinitely in all directions. In accordance with the extravagant tastes of deities, the artificer has hung a single glittering jewel in each "eye" of the net, and since the net itself is infinite in dimension, the jewels are infinite in number. There hang the jewels, glittering "like" stars in the first magnitude, a wonderful sight to behold. If we now arbitrarily select one of these jewels for inspection and look closely at it, we will discover that in its polished surface there are reflected all the other jewels in the net, infinite in number. Not only that, but each of the jewels reflected in this one jewel is also reflecting all the other jewels, so that there is an infinite reflecting process occurring.'"
